Remember that the BODY element is itself scrollable, so if you
just say ":scrolled-content" as a selector, it will apply it to
the whole document canvas. To specify this pseudo-class for all
OTHER scrollable areas, use "body :scrolled-content" (Descendent selectors.)

Netscape 6 applies this to the SELECT element contents, but not
to TEXTAREA elements. I find that odd. 8-}
